Title: Control circuit for pwm rectifier
Inventor: FUJIKURA MASANOBU
IPC: H02J9/06
Filed: 1990-05-11
Abstract: PURPOSE:To suppress a rise in a DC voltage by detecting a state of DC overvoltage of a PWM rectifier due to a current from a bypass circuit, by making the PWM rectifier conduct an inverter operation by switching it from an ordinary charging mode over to a regenerative mode on the basis of a signal of this detection and by returning thereby an effective power stored in a DC circuit onto the AC input side. CONSTITUTION:When a DC overvoltage is detected in a state wherein an inverter output and a bypass output lap over, an analog switch 25 is turned ON through an AND gate 223, an NAND gate 225, a flip-flop 226 and an NOT circuit 227 and a voltage adjustment signal is made low forcedly through an addition circuit 23 and an inversion circuit 24 so that a PWM rectifier 4 be set in a regenerative mode. Thereby an input current set value of the PWM rectifier is decreased and the PWM rectifier is made to conduct a regenerative operation, so that an effective power stored in a DC current thereof be returned onto the AC input side (commercial power source side). Accordingly, the state of the DC overvoltage of the PWM rectifier is suppressed.

Title: Laminated ceramic capacitor
Inventor: INOMATA YASUYUKI
IPC: H01G4/30
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To provide a small-sized large capacity capacitor having a desired CR product by making the ratio of a single-layer single-particle part, which is formed of a single ceramic particle in a single dielectric layer, a specific value or more. SOLUTION: The ratio of a one-layer one-particle part, which is formed of one ceramic particle in one dielectric layer, is 20% or more. The dielectric layer may have a thickness of 5 μm or more. However, a ceramic particle having a thickness of 5 μm or less and forming the dielectric layer is preferably having an average particle diameter of 3.5 μm or more. The reason for a thickness of 5 μm or less is that when the thickness of the dielectric layer is 5 μm or less, the CR product of a laminated ceramic capacitor deteriorates conspicuously. The one-layer one-particle means like parts A and B where a dielectric layer 12 between inner electrodes 10 and 10 are composed of one of ceramic particles A and B, respectively.

Filed: 1980-09-02
Abstract: PURPOSE:A monomer gas is supplied from the porous pipe that is set near on the surface of the running film and the addition polymerization of the monomer is effected on the running film in the discharge chamber to form a thin film, thus producing a composite semipermeable membrane efficiently. CONSTITUTION:As a monomer gas is being fed from the porous pipe 8 that is set near the film on the roll, evacuation is effected to keep the pressure in the chamber 1a 0.1-10Torr and discharge is effected between electrodes 2 and 3. A part of electrons formed passes through the anode 2 to reach the surface of the film running on the roll 7. The monomer fed from the porous pipe 8 is activated by the collision with the electrons to polymerize and form a high-polymer thin film on the running film f. Since the porous pipe 8 is set near the film on the roll, the concentration of the monomer gas becomes high on the film surface to accelerate the formation of the high-polymer thin film.

Title: Automatic ultrasonic flaw detecting method for solid-core insulator
Inventor: MATSUO JUNICHI
IPC: G01N29/04
Filed: 1989-05-17
Abstract: PURPOSE:To improve the detecting accuracy of an inner defect by suppressing the height of forest-shaped echoes which are inevitably generated in solid-core insulators to a lower value. CONSTITUTION:Probes 3 are brought into contact with deflected positions which are deviated to the outside from the central axis of the insulator at both end surfaces of upper and lower parts of a solid-core insulator. The probes 3 are turned around the central axis of the insulator by one time. Thus the inside of the solid-core insulator 1 undergoes ultrasonic wave flaw detection. The contact positions of the probes 3 to both end surfaces of the upper and lower parts of the solid-core insulator 1 are made to be the deflected position which are deviated from the central axis of the insulator. In this way, the height of a forest-shaped echo can be made to be 1/2 or lower than the height when the contact positions of the probes 3 are made to be the position on the central axis of the insulator. For example, the probes 3 at both end surfaces 2 are alternately selected with a multiplexer 4 which is an electronic switching device, and the waveform of a flaw is outputted through an ultrasonic-wave flaw detector 5. The analog waveform outputted from the flaw detector 5 is digitized with an A/D converter 6. The signal is inputted into a computer 7 and processed with software. Only the waveform of the defect is detected.

Abstract: PURPOSE:To attain a perfect visual feedback by performing the arm control of a robot by using the distance (distance picture) between each point of an object and a certain fixed point and a picture obtained on the robot arm to detect the 3-dimensional position, posture and form of the object. CONSTITUTION:A distance picture detector 19 obtains the distance picture of the object 11 and sends it to an image processor 21. The processor 21 also receives a picture viewed from the robot arm side from a picture detector 20 set on the arm 17. Based on both pictures, the form, position and posture of the object 11 are recognized respectively. The control signal is sent to a robot controller 18 to perform the visual feedback control so that the arm 17 is corrected to be at a correct position to the object 11. The processor 21 differentiates the distance picture signal to produce a jump edge picture and separates the object 11 into the areas closed by the jump edge for the recognition of the object 11. Thus the centroid and inclination of an important plane are also detected from the separated areas.

Title: Control method of idle speed control device
Inventor: ITOU YOSHIYASU
IPC: F02D41/00
Filed: 1983-07-08
Abstract: PURPOSE:To prevent an engine speed from decreasing, by setting the lower limit of opening of a control valve to a value calculated on the basis of a study value and the running condition of an automobile during feedback control of the idle speed control valve. CONSTITUTION:An electronic control device 31, performing feedback control by the control routine of an idle speed control (ISC) valve, decides an engine for whether or not it is in a hot idle period. If it is in the hot idle period, duty ratio D is limited to a value above the lower limit Dmina in the hot idle period. Then a study value Dg is updated. If not in the hot idle period, the duty ratio D is limited so as to become a value above the lower limit Dminb by calculating the lower limit Dminb of the duty ratio D in a non-hot idle period on the basis of the study value Dg. In such way, a speed of the engine immediately before completion of its deceleration can be prevented from decreasing.

Title: Rootcrop harvester
Inventor: KAWAGUCHI HIROMICHI
IPC: A01D25/04
Filed: 1995-05-23
Abstract: PURPOSE: To provide a rootcrop harvester enabling rootcrops to be easily pulled off the soil vertically upward by a gripping belt according to its advancing speed. CONSTITUTION: This rootcrop harvester is so designed as to be equipped with a means to change the tilt angle of a digging gripping belt on the harvester in the longitudinal direction of the vehicle to ensure rootcrops to be pulled off vertically by the belt according to the traveling speed of the harvester. To pull rootcrops off the ground vertically, the tilt angle θ of the belt is made relatively small when the vehicle speed is high (Fig. (a)), while the angle relatively large when the vehicle speed is low (Fig. (b)). For the belt tilt angle changing means, use of a manually operational handle can easily control the tilt angle θ. In particular, when the field soil is hard and rootcrops are hard to pull off the soil, the vehicle is slowed down; therefore, relatively large tilt angle θenables rootcrops to be relatively easily pulled off.
